Example Pump Controls in InfoSewer and H2OMap Sewer

Five ways to control the pump by controls in InfoSewerH20Map Sewer. Here are a few examples and important features of the various InfoSewer Pump Controls. A pump in InfoSewerH20Map Sewer uses a Newton-Raphson iteration process for 50 iterations or until the successive iterations between pump flows are 0.001 cfs.

Pump volume – control the pump by the pump volume (cubic feet or cubic meters). The on and off settings, pump curve and the iteration process applying to pumps are the controlling simulation features.

By Level– control the pump by the pump level or depth ( feet or meters). The on and off settings, pump curve and the iteration process applying to pumps are the controlling simulation features.

By Discharge – control the pump by the pump pattern in flow units. The pump pattern (discharge), pump curve and the iteration process applying to pumps are the controlling simulation features. The pump speed adjusts to main the pump pattern.

By Inflow – control the pump by the inflow to the Wet Well. The Wet Well inflow, the iteration process applying to pumps are the controlling simulation features. The pump flow equals the inflow to the Wet Well and the Wet Well stays at a constant level.

By Time – control the pump by the time speed pattern. The pump curve is used when the pump is turned on by the pattern.

I have noticed based on email questions and postings to the SWMM LIst Sever (a great resource hosted by CHI, Inc.) that many SWMM 5 users do not know about the really outstanding documentation on SWMM 5 posted on the EPA Website https://www.epa.gov/water-research/storm-water-management-model-swmm It consists of two now and in the near future three volumes on Hydrology, Water Quality, LID’s and SuDs and Hydraulics. The documentation is fantastically complete with detailed background on the theory, process parameters and completely worked out examples for all of the processes in SWMM5. It is truly an outstanding aid to modelers and modellers worldwide. It would benefit you to read them (if you have not already downloaded the PDF files). Thanks for reading this post
